Abstract:
We report the shape-preserving conversion of self-assembled CaCO3 microtubes to PbCO3 and MAPbBr3 perovskite. The first step induces the growth of cerussite needles on the outer surface. When further converted, these hedgehog-like structures become fluorescent. Additional spatial control of the process yields Janus tubes of CaCO3 and perovskite segments.
